    Default Engine Block

    Its cast iron, not a material for the inexperienced to be attempting. If it showed up at my shop I would pass on it. No way to put a gaurantee on that.

    I 2nd the locknstitch. Yes you could mig weld it but first you need a $75.00 spool of cast iron mig wire. Deff not a first time job. If you were by me i would do it...Bob

    I agree with fabricator ( You just cannot guarantee it )

    A Metal master, The process you chose to weld it with is not as significant, Its more about proceedure, how far to weld, when to peen ETC.

    Use the Lock n stitch process and don't take chances with the block. Threw a rod on track loader and put 4 inch hole in block. That's been six years ago and not a problem at all.

    Default non stressed

    Hello if the piece is not under any stess or wear if it is the part between the bottom of cylinders and where the oil pan bolts just weld it it's job mostly is to keep the oil from leaking out.

    Default flame spray

    I have used a flame spray torch made by ESAB which is the only way I would repair cast iron. For more details on how it works you could go online and look it up. But I have had a lot of success with it. Basically it's a oxygen and acetylene torch with a built in hoper and when depress the trigger you start spraying metal which has the same properties has the cast iron base metal so it will cool at the same rate so you don't get any crakes. Its truly awesome. I know my company stocks them at www.airweld.net but you can find them all over. Good luck.
